Yes. In fact, I did it that way first, and then on the console. For what
it's worth, I only have headless boxen at the ready, so the other run
looked like this:

    fbsd% ipython notebook --no-browser --port=8080

    osx% ssh -L 8080:localhost:8080 fbsd

    [open http://localhost:8080/ in browser on osx]

It's curious that you see different results between the console and
browser front-ends. I don't know enough about the ipython architecture
to infer useful next steps, but that seems significant.
